What is the best remedy for constantly itchy skin?

Although each person's skin reacts differently to treatment for dry, itchy skin, some of the most effective remedies include applying petroleum jelly, moisturizer or hydrating hand sanitizer to the affected area, according to WebMD. An oatmeal bath may also help relieve itching and moisturize the skin.

Apply moisturizer regularly to soothe itchy, dry skin and help the skin hold water, recommends WebMD. Moisturizers with ceramides, lanolin and mineral oil hold onto water absorbed in the skin to retain moisture.

Preventative measures include applying latex gloves when using harsh cleaning chemicals and vacuuming regularly to rid the home of dust mites.
